I filled up at the Caltex in Unanderra this afternoon then went for a ride up Macquarie Pass and back. I pulled up at the bottom to check my phone and noticed that the engine was idling a bit rough. Put it in first and let the clutch out a bit and it went dead . Started it up again, engine still idling a bit rough. Let it idle for a bit, giving it some revs when it sounded like it might die. Gave it a bit more throttle and and pulled away. When I got back home everything seemed ok...So possibly bad fuel? Something in the fuel that got caught in the fuel filter? The bike has been trouble free so far and it had a minor service 500km ago. Thoughts anyone?
